Problems solved by technology

[0004] Existing PVC plastic special-shaped plates have the following defects: 1. High cost; 2. Poor thermal stability, hardening and brittle at low temperature, easy to soften and relax at high temperature; 3. Poor processing performance, impact resistance and aging resistance ; 3. Release harmful substances during the production process and produce hazardous waste products. The finished product will release dioxin acid gas at high temperature, and its additives will gradually volatilize during use, polluting the air

Abstract

The invention discloses a plastic section bar and a technology for processing the same. The plastic section bar comprises, by weight, 100-120 parts of polyvinyl chloride resin, 2-3 parts of organic tin carboxylate, 1-2 parts of polyacrylate resin, 8-10 parts of chlorinated polyethylene, 5-10 parts of activated calcium carbonate, 4-6 parts of rutile type titanium dioxide, 0.5-1 part of polyethylene wax and 0.5-1 part of antibacterial and bacterium inhibition additives. The plastic section bar and the technology have the advantages that the plastic section bar is low in cost and good in heat stability, weather resistance, toughness and uniformity and is smooth; the rigidity of the plastic section bar can be improved, the plasticizing quality can be enhanced, and the appearance can be improved; antibacterial and bacterium inhibition effects can be realized by the plastic section bar, and accordingly the plastic section bar is applicable to sterile places.

Description

technical field [0001] The invention relates to the technical field of plastic profiles, in particular to a plastic profile and its processing technology. Background technique [0002] Polyvinyl chloride, referred to as PVC in English, is a thermoplastic resin polymerized by polyethylene under the action of an initiator. The molecular weight of industrially produced PVC is generally in the range of 50,000 to 120,000. It has large dispersibility. The molecular weight increases with the decrease of polymerization temperature, but its stability to light and heat is poor. , it will be decomposed to produce hydrogen chloride, and further autocatalytic decomposition will cause discoloration, and the physical and mechanical properties will also decline rapidly. In practical applications, additives must be added to improve various performances. [0003] PVC plastic sheet is already a very popular new type of light-weight decorative material in the world today, and it is a popular p...
